Washington, D.C.-area punk and metal bassist Vance Bockis has died at the age of 50. The musician, who played in such bands as The Obsessed, 9353 and Pentagram, in addition to fronting The Factory, passed away at his home in Fairfax County, Virginia, from complications following shoulder surgery.

He entered the hospital to be treated for rotator cuff surgery and was preparing to play with the re-formed 9353, who recorded new material earlier this year, his family told WTOP.

Bockis was as well known for his music as he was for a heroin addiction, a condition that left him emaciated and contributed to The Factory losing a potentially big break with CBS Records. His recovery was the subject of a 2010 documentary entitled "Shift".

A service for Bockis will be held Thursday, September 13th at 6 p.m. at Fairfax County Memorial Funeral Home.
